aspnet_compiler.exe [HttpCompileException]: External component has thrown an exception.

I was getting this error during the pre-compilation of website:
[HttpCompileException]: External component has thrown an exception.

the cause of the problem was incorrect references  in web.config.

Here's rebuild.bat file for precompilation website without opening Visual Studio 2008:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler.exe -v "/beta " -p "beta\\" -u -f -d -fixednames "PrecompiledWeb\beta\\" -errorstack  
sndrec32.exe /play /embedding c:\tools\saundz\phone_1.wav 
pause

compilation of about 500 classes taking about 15 min , sndrec32 string for notifying that build complete.

variables in dot net regular expressions

search pattern :  \s*<Merchant>\s*<ID>(?'d'.*?)</ID>
replace pattern:
NF:${d}.xml
<Merchant>
        <ID>${d}</ID>


As you can see d is variable declared in  search pattern and used into replace:
Also here is interpretation of search pattern :
Options: dot matches newline; free-spacing

Match a single character that is a “whitespace character” (spaces, tabs, line breaks, etc.) «\s*»
   Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «*»
Match the characters “<Merchant>” literally «<Merchant>»
Match a single character that is a “whitespace character” (spaces, tabs, line breaks, etc.) «\s*»
   Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «*»
Match the characters “<ID>” literally «<ID>»
Match the regular expression below and capture its match into backreference with name “d” «(?'d'.*?)»
   Match any single character «.*?»
      Between zero and unlimited times, as few times as possible, expanding as needed (lazy) «*?»
Match the characters “</ID>” literally «</ID>»

remove banners in google chrome

I'm going to try privoxy. this little proxy server that allows to remove ads by  specifying patterns.

Actually firefox Adblock Plus  did perfect job,but chrome is much fester .

Probably it's possible to modify privoxy (it's open source) for working with banners lists like EasyList (USA)
http://easylist.adblockplus.org/adblock_rick752.txt
And add some new pages to privoxy, that allows to add new patterns on fly.

Or just wait when adblock will be ported on Google Chrome :)
what do you think?
